22 of each of the auxiliary female fasteners 2 is locked onto the
locking piece 12 of each of the auxiliary male fasteners 1 to
secure the ornamental cover 4 to the wheel disk 3. In such a
manner, when the ornamental cover 4 is mounted on the wheel disk 3,
the primary fastening members 43 of the ornamental cover 4 are
locked onto the spokes 32 of the wheel disk 3, and each of the
auxiliary female fasteners 2 of the ornamental cover 4 is locked
onto each of the auxiliary male fasteners 1 of the wheel disk 3, to
secure the ornamental cover 4 to the wheel disk 3 in a double
locking manner, so that the ornamental cover 4 is secured on the
wheel disk 3 solidly and stably.
[0020] In the preferred embodiment of the present invention, the
male body 11 and the locking piece 12 of each of the auxiliary male
fasteners 1 are formed integrally.
[0021] In the preferred embodiment of the present invention, the
locking piece 12 of each of the auxiliary male fasteners 1 and the
locking groove 22 of each of the auxiliary female fasteners 2 have
the same trapezoid cross-sectional profile. The locking piece 12 of
each of the auxiliary male fasteners 1 has two oblique faces 121
and a plane 122 located between the two oblique faces 121. Each of
the two oblique faces 121 of the locking piece 12 and the first
side of the male body 11 are arranged to have an acute angle with
an arcuate corner. It is to be noted that, a larger angle and a
smaller angle are defined between each of the two oblique faces 121
of the locking piece 12 and the first side of the male body 11, and
the acute angle means the smaller angle between each of the two
oblique faces 121 of the locking piece 12 and the first side of the
male body 11. The plane 122 and each of the two oblique faces 121
of the locking piece 12 are arranged to have an acute angle with an
arcuate corner. The locking groove 22 of each of the auxiliary
female fasteners 2 has two oblique faces 221 and a plane 222
located between the two oblique faces 221. Each of the two oblique
faces 221 of the locking groove 22 and the first side of the female
body 21 are arranged to have an acute angle with an arcuate corner.
The plane 222 and each of the two oblique faces 221 of the locking
groove 22 are arranged to have an acute angle with an arcuate
corner.
[0022] In the preferred embodiment of the present invention, the
locking piece 12 of each of the auxiliary male fasteners 1 and the
locking groove 22 of each of the auxiliary female fasteners 2 have
the same isosceles trapezoid cross-sectional profile.
[0023] In the preferred embodiment of the present invention, the
locking piece 12 of each of the auxiliary male fasteners 1 and the
female body 21 of each of the auxiliary female fasteners 2 are made
of flexible material. Preferably, the locking piece 12 of each of
the auxiliary male fasteners 1 and the female body 21 of each of
the auxiliary female fasteners 2 are made of plastic material. In
such a manner, the locking groove 22 of each of the auxiliary
female fasteners 2 is snapped and locked onto the locking piece 12
of each of the auxiliary male fasteners 1 easily and smoothly by

its elasticity, so that the locking piece 12 of each of the
auxiliary male fasteners 1 is locked in the locking groove 22 of
each of the auxiliary female fasteners 2.
[0025] Accordingly, when the ornamental cover 4 is mounted on the
wheel disk 3, the primary fastening members 43 of the ornamental
cover 4 are locked onto the spokes 32 of the wheel disk 3, and each
of the auxiliary female fasteners 2 of the ornamental cover 4 is
locked onto each of the auxiliary male fasteners 1 of the wheel
disk 3, so as to provide a double locking function to secure the
ornamental cover 4 to the wheel disk 3, so that the ornamental
cover 4 is locked onto the wheel disk 3 solidly and stably, thereby
preventing the ornamental cover 4 from being detached from the
wheel disk 3.
[0026] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the scope
of the invention.
